Situational Awareness & Control 7.1 Objective


The objective of this Chapter is to outline the main requirements and considerations that should be included in a process to design and manufacture a Situational Awareness and Control system for a MASS.


7.2 Scope


7.2.1 A situational awareness and control system for a MASS can include the onboard sensors and offboard information sources, communications links and control logic that allow the MASS to operate safely.


7.3 Functional Objectives


7.3.1 The goal of Situational Awareness and Control is to ensure that the MASS has sufficient information, interpretation and control of its position and systems, to enable it to be as safe as a manned counterpart operating in similar circumstances. Any decision making that impacts safety and is performed by the MASS (i.e. independent of a human operator) should have been adequately demonstrated to be commensurate with that which a competent seafarer would correctly perform in the same circumstances.


7.3.2 A Risk Assessment shall be undertaken using an appropriate method, e.g. Failure Mode Effects Analysis (FMEA), in order to identify the risk levels associated with the MASS and its operation.


7.3.3 Internal and External sensors may be used to monitor the state of the platform and the external environment.


7.3.4 It is necessary to have the ability to interpret sensor data in terms of its immediate or impending impact on MASS performance, and its direct or indirect effect on the safety of the MASS, surrounding structures and vessels, humans and the environment.


7.3.5 The control system shall be designed and constructed to:


n Enable its operation in all RFOC; n Operate in a predictable manner with a level of integrity commensurate with operational and safety requirements; n Ensure the watertight and weathertight integrity, to meet buoyancy and stability requirements; n Minimise the risk of initiating fire and explosion; n Enable the maintenance and repair in accordance with the maintenance philosophy.


7.3.6 Operators shall be provided with adequate access, information and instructions for the safe operation and maintenance of the control system.
